ROLL-HOLDING A'r'rAoHMniir T.

Application filed January To all whom it may concern: v I r 7 Be itknown that I, RAYMOND A. BIRMING- HAM, a citizen of the United States,residing at Buena Vista, in the county of Rockbridge and State ofVirginia, have invented new and useful Improvements in Roll HoldingAttachments, of which the following is a specification.

The object-of this invention is the provision of a typewriting machineor an adding machine with a holding device for a roll of paper made upof detachably connected sheets and arranged so that the same may be fedaround the platen roller for typing, and thus obviate the necessity ofseparate sheets of papers in the use of the machine.

A further object is the production in a device for this purpose of aframe which is adjustably secured on the carriage of a typewriter or onan adding machine and which has iournaled thereon a roll on which thepaper to be typed is arranged and which also carries spring influencedcompensating means for engaging the roll of paper for sustaining thesame properly upon the'paper carrying roll, and in which means is alsoprovided for holding the paper roll from side movement on the receivingroll therefor, as well as means for turning the said paper receivingroll when the paper is to be fed therefrom.

To the attainment of the foregoing and other objects which will presentthemselves as the nature of the invention is better run derstood,reference is to be had to the drawings which accompany and which formpart of this application.

the drawings Figure 1 is a rear elevation of a typewriting machineillustrating the application of the improvement thereon.

Figure 2 is a sectional view approximately on the line 22 of Figure 1.showing the manner in which the paper is fed around the platen roll ofthe machine.

Figure 3 is a sectional view on the line 3-3 of figure 2.

The remaining Figures 4, 5 and 6 illustrate details.

In the drawings, I have illustrated my improvement in connection with anordinary typewriting machine, but it is to be understeed that the sameis applicable to adding machines or to any other class of machines 15,1924. semi Nd. esaseb;

or devices on which fed. 5 p 7 Referring now to the drawings in detail,the numeral 1 designates an ordinary type writing :machinie, 2 themovable carriage :thereof, and 3 the platen-roll. Secured on paper to betyped is the rear ofthe carriage by clamping means 4, is'the frame 5 ofthe improvement. The clamping elements it are adjustably. secured bymeans 6 to the uprights 7 of the frame. The bcdy of the frame,preferably comprises only the uprights 7, but if desired, suitable andpreferably adjustable means may connect the said uprights. The uprights7, at their upper ends are provided with bearings 8 for the shaft 9 of apaper carrying roll 10. A roll of paper may be directly wound around theshaft, if desired. The hearings 8 preferably have their upper facesopen, but the said upper faces are closed by clamps 11 for effectivelysustaining the shaft 9 therein. The shaft 9 has on both of its endsknurled disks 12 and 13 respectively whereby the said shaft and its rollmay be turned by hand. The paper which is wound around the centralportion of the shaft or the roll 10 thereon, is indicated by the numeral14, and this roll of paper is preferably of sheets of equal lengths,divided from each other by perforated or other weakened lines. On thecentral part of the shaft or on the roll 10 there are disks 15 and16resnectivelv. These disks carry outwardly directed hubs and throughthese hubs there are passed binding elements 18. The disks 15 and 16contact the ends of the roll of paper and hold the same fromlongitudinal movement on the shaft 9 or on the roll 10, when the latteris employed. Suitable means, such as sleeves 19, are arranged upon theshaft and contact with the bearings 8, binding elements 20. passingthrough the said sleeves.

Each of the standards 7, at a suitable distance above its lower end, hasan outwardly directed flange or angle portion 21, and the said angleportions are preferably provided with upwardly directed tubular sockets22. In each of these sockets there is received coiled pressure spring 23that is secured to and exerts a pressure against the ends of what I willterm a compensating rod or bar 24:. The rod 24 is provided with eyes 25through which the standards 7 are passed, and the rod contacts with theroll of paper 14 to prevent the sagging thereof when the same decreasesin diameter, as the outer portion thereof is fed around the platenroller 3 of the machine 1.

My improvement is of an adjustable nature, so that various Widths ofpaper rolls may be arranged thereon. The rolls may constitute a greatnumber of sheets of ordinary typewriting paper, so that a large volumeof Work may be typed thereon Without necessitating the feeding ofseparate sheets to the platen roll of the machine, it being merelynecessary to detach each sheet after the same has been typed upon.

Having described the invention, I claim 1- The combination with atypewriter or similar machine, of spaced uprights adjustably secured tothe rear of the carriage thereof, a shaft journalecl in bearings at theupper ends of the uprights, means securing the shaft in the bearings,means on the shaft preventing the longitudinal movement thereof throughthe bearings, knurled operating disks on the ends of the shaft, saidshaft designed to have Wound therearound a roll of paper which is to befed to the platen roll of the machine and to be typed upon, adjustablemeans on the shaft for enpurgingthe ends of the paper roll, a barslidable on the uprights. a socket on each upright a coiled spring; ineach socket contacting the ends of the bar for forcing the same againstthe paper roll. for the purpose set forth.

In testimony whereof I atlix my signature.

RAYMOND A. BIRMINGHAM.
